How can a good God allow evil and suffering?
There may be several reasons for suffering. A major factor is our fallen, sinful world. Because of sin, throughout the ages, the perfection and goodness of the world is tainted. We experience illness, disease, natural disasters, hunger, and all types of suffering.
As mortals, we cannot know all of God's reasons. But, God loves us enough to give us free will. We are not robots. As a result, people make mistakes. People turn away from God's perfect goodness through sin.
Thus, our own choices sometimes produce evil over good. It is impossible for God to have created man with free will and evil not be a consequence. Also, the choices of others (including previous generations) can produce suffering. The consequences of bad choices sometimes affect not only the person who makes the wrong choice but also their family, friends, and sometimes even society.
The Old and New Testaments make it clear that suffering can be a result of God's discipline in our lives—similar to the discipline a loving parent has for his child. A loving parent stops a child from putting his hand on a hot stove. The child "suffers" at the moment by being denied access and by the temporary pain of a spanking. But the parent sees the "big picture" and disciplines the child. So, too, can God discipline us. Hebrews 12:10-11 illustrates this point: "...but God disciplines us for our good, that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it."
Suffering is God's megaphone to a deaf world. Suffering can produce benefits greater than the suffering itself. It can strengthen people, lead people to faith, help us to appreciate the good, and be a tool to influence others. Indeed, suffering can mold us. "Suffering produces perseverance... character... hope...." (Romans 5:3-5). And as apostle Peter relates, "...though now for a little while you may have had to suffer grief in all kinds of trials. These have come so that your faith—of greater worth than gold, which perishes by fire—may be proved genuine and may result in praise, glory and honor when Jesus Christ is revealed" (1 Peter 1:5-7). The actual trials of faith are worthwhile and precious as is faith itself! Our faith is strengthened as we rely on Christ to see us through troubling times.
We may not know the reason for suffering in any individual situation. But we can affirm, with relief and joy, that in "all things God works for the good of those who love him" (Romans 8:28). The Psalms are full of cries for deliverance from trouble as well as the assurance that God is with us and will deliver us from suffering.
It is the knowledge that God sent His only son to suffer and die for us that our sins are forgiven and that our ultimate suffering will be relieved. As Paul Little proclaims, God is "not only aware of suffering—he feels it. No pain or suffering has ever come to us that has not first passed through the heart and hand of God...Comforting are the words of Isaiah the prophet, foretelling the agony of Christ: 'He was despised and rejected by men, a man of sorrows, and familiar with suffering' (Isaiah 53:3)."
Actually, Christianity is the only religion or worldview that has an answer to evil and suffering. Eastern religions ignore evil; Darwinism and Communism rely on it; and Islam has a superficial view of it. Only Christianity provides an answer—that we are living in an abnormal world which God will restore. For more on this, see our Christian Cram Course.
